and then you have strauss, extraordinary piece. the most challenging of all. string orchestra work. 23 solo instrument, no violin section, now viola section; everybody is responsible for their part in this piece. the challenge is something that i felt not only that we could do , absolutely could do, but i wanted to show off. i can't tell you how aware i am of the audience. not only what i hear but their vibes, so strong. i have been doing this for a long time. i kind of make them feel what i want them to feel.
